Just had this one on the phone:
(2min into the conversation, I was beginning to lose my patience by that point)
'Doctor': Are you ok with all fetishes?
Me: Well, it depends, what's yours?
'Doctor': I was thinking of the following scenario: I am the doctor, you're the patient, you say you have a sore throat, I look in your throat and you give me a blowjob.
Me: Sounds fun...
'Doctor': Do you still have your tonsils? It's part of my fet..
Me: *puts the phone down*
